How It Works


This light works from dusk to dawn. It is recharging batteries during the daylight hours and operates during the nighttime hours.

Unlike a weak single “ON” and “OFF” light pattern, we use 7 distinct light patterns which make it nearly impossible for the geese to adapt to a single pattern.


Why it works:


Uv Spectrum

Geese see in the same visual spectrum as humans and also in the UV spectrum. Our light operates in both spectrums to achieve its outstanding results.


Protection from Predators

Geese are wild animals that live to survive and survive to live. As with any wild animal, geese place a high priority on feeding and protecting themselves from predators. During the daylight hours geese will graze on most grassy areas which provide a hassle free environment. Geese will graze all day long to support their nutritional needs as grass provides little nutritional value, therefore they require as much as possible.

Geese, being wild animals, are always in survival mode by being on the watch for predators and trying to minimize their energy output. While geese are grazing, there will always be one or two “scouts” in the flock watching for predators.

Geese have very keen eyesight. So during the day, when a predator is spotted, the “scouts” will alert the flock by squawking, and they will immediately move to the nearest waterway or take flight if no water is in the immediate vicinity. Taking flight is an expensive option for geese because it requires so much energy to do so. That is why it is used as a last option.

Their first line of defense is their eyesight.

Their second line of defense is the waterway.

Once in the water they will not leave until that line of defense is penetrated. Their final defense measure is to take flight. Flight is an expensive energy choice, but one that is required for survival.


Night Time Hours

During the nighttime hours, geese will move into the water to roost or rest. The waterway provides a secure location away from predators during the night time hours. This is where they will sleep for the evening while a few “scouts” will keep watch for predators. At this point their only line of defense is their eyesight and the protection of the waterway boundary.


How Geese See

Their eyesight is similar to humans.

Imagine if you will, you wake in the middle of the night. You can only see outlines of objects in your house. Your vision has adapted to the nighttime darkness and as you enter the kitchen you turn on the light. You squint your eyes and it is difficult to see for a moment because of the change in lighting. After you have finished up in the kitchen, you now turn off the light. Your eyesight is again hampering you ability to move around. All you can see now are very dark voids and almost no shadow outlines of furniture.

This is because your nighttime vision has not yet been restored. It will take as much as 30 minutes for you to restore you nighttime vision.


Why The Denier ™ Works so Effectively

This is exactly the same scenario which happens to the geese while they roost on the waterway while our lights are active. THE DENIER ™ resets their nighttime vision.


The Denier ™ will do this repeatedly.

The lights will temporarily disable their nighttime defense to spot predators. If geese cannot spot predators, they cannot defend themselves, and if they cannot spot predators, they cannot sleep. If geese cannot spot predators or sleep, they will move to another location where they can find security.


Say Goodbye to Geese

If geese are not roosting on the waterway at night, they will not be on your property in the morning hours.

They will remain at their current location until there is a threat which requires them to take flight and leave.
